The Benguela Langschnabellerche ( Certhilauda benguelensis ) is a large species from the lark family. It is larger than a skylark , has a longer and more curved bill, and is a thrush-like shape. The distribution area of the Benguela Langschnabellerche is in western Africa. There are two subspecies. The Benguela Langschnabellerche has long been classified as a subspecies of the Langschnabellerche . Due to its genetic data, its slightly different body structure and its different song, it is classified as an independent species today.
features
The Benguela long-beaked lobster reaches a body length of about 18 to 20 centimeters and weighs between 35 and 53 grams. The beak measures 2.1 to 2.4 centimeters measured from the head. There is no gender dimorphism. However, males are on average larger than females, are correspondingly heavier and have a significantly longer beak.
The Benguela long-beaked lark is a very light colored lark. The top of the body is light gray-brown. A light stripe above the eye runs above the eye. The chin and throat are whitish gray with diffuse light vertical stripes. The front breast is slightly more strongly striped on a light background. The rest of the underside of the body is creamy white with a slight brown tinge.
Distribution area of the subspecies
There are two subspecies:
- C. b. benguelensis - ( Sharpe , 1904) : Occurrence from the south-west in Angola to the north-west of Namibia.
- C. b. kaokoensis - Bradfield , 1944 : Occurrence in northwestern Namibia, the range includes the Kaokoveld , the southern limit of the range is the Brandberg massif .
Benguela long-beaked birds are resident birds and occur almost exclusively in stony hill country.
Way of life
The habits of the Benguela long-beaked lark have not yet been conclusively investigated. It feeds on insects and seeds. Like all larks, it is a ground breeder. So far, nests have only been found in May. The bowl-shaped nest is built under the protection of tufts of grass or stones.
